Climate change is one of the most pressing challenges facing the world today. The impact on the global economy is vast and complex. Rising global temperatures are causing extreme changes in weather patterns, exacerbating natural disasters, and harming the agriculture, fisheries and tourism sectors. The increasing frequency and intensity of natural disasters, such as storms, floods and droughts, are causing significant economic losses. According to a World Bank report, vulnerable countries, especially in tropical regions, could experience a decline in GDP of up to 15% by 2050 due to the impacts of climate change. This affects investment, job growth, and resource availability. The agricultural sector is one of the most affected. With increasing temperatures, yields of many commodities have decreased. A study shows that the risk of crop failure could increase by up to 20% by 2050. This not only increases food prices, but also has the potential to trigger a global food crisis, especially in developing regions. In the fisheries sector, changes in sea temperature and water acidity threaten the survival of many fish species. This will impact the livelihoods of millions of fishermen and food security in countries that depend on marine resources. A sustainable management process is a major concern to maintain ecosystem balance and ensure food supply. The tourism industry is also feeling the negative impacts of climate change. Previously popular destinations may no longer be attractive due to extreme weather or natural disasters. This will reduce the number of tourists and, in turn, reduce economic revenues from this sector. Countries that depend on tourism, such as the Maldives and Barbados, will feel the impact more heavily. From a health perspective, climate change may increase the risk of infectious diseases, leading to higher health expenditures and reduced productivity. For example, warmer weather can increase the spread of diseases such as malaria and dengue fever, having serious impacts on health systems and economies. Several countries are responding to this challenge by investing in green technology and renewable energy. The switch to clean energy sources such as solar and wind not only reduces greenhouse gas emissions, but also creates new jobs and drives economic growth. It is hoped that initiatives like this will bring in investment and help reduce economic instability caused by the climate crisis. Investment in climate-resilient infrastructure is another defensive measure. By adapting, countries can reduce economic losses and increase resilience to disasters. However, this requires international cooperation and adequate funding for the most vulnerable developing countries. In facing climate change, global collaboration is essential. The Paris Agreement provides a framework for countries to commit to reducing emissions, but implementation requires real commitment and action. Strengthening sustainable economic policies will help the world better deal with these changes. Every small action can have a big impact. Individual contributions, such as reducing waste, using public transport or switching to a sustainable lifestyle, are now increasingly prioritized. Communities need to be encouraged to understand the importance of their role in dealing with climate change and its impact on the global economy.
